BPF: Implement build time feature flag for libbpf

For trunk stable development, we use a build time feature flag for the
libbpf functionality to be added to bpfloader. For now, simply stub it
out.

This approach will allow merging and testing of libbpf functionality
without changing the binaries produced with the feature disabled going
forward.
